Coherent Phonon Pairs and Rotational Symmetry Breaking of Charge Density Wave Order in the Kagome Superconductor CsVSb
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +4
In this work, we perform ultrafast time-resolved reflectivity measurements to study the symmetry breaking in the charge-density wave (CDW) phase of CsVSb. By extracting the…

Absence of Phonon Softening across a Charge Density Wave Transition due to Quantum Fluctuations
Yubi Chen, Terawit Kongruengkit, Andrea Capa Salinas +9
Kagome metals have emerged as a frontier in condensed matter physics due to their potential to host exotic quantum states. Among these, CsV3Sb5 has attracted significant attention…

Phase-Separated Charge Order and Twinning Across Length Scales in CsVSb
Jayden Plumb, Andrea Capa Salinas, Krishnanand Mallayya +9
We present X-ray scattering studies resolving structural twinning and phase separation in the charge density wave (CDW) state of the kagome superconductor CsVSb. The three-…
